Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package executes disguised helper code rather than merely validating it. The helper creates persistent state, builds a binary, starts a detached local service, and initiates SSH automatically. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-11T15:29:45.396Z - **Finished:** 2026-09-11T15:30:37.131Z - **Download time:** 253 ms - **Static scan time:** 28 ms - **AI review time:** 51453 ms - **Total time:** 51735 ms The recorded confidence comes from the underlying analysis.

The helper creates persistent state, builds a binary, starts a detached local service, and initiates SSH automatically. - **Trigger:** npm postinstall during package installation - **Impact:** An install unexpectedly compiles and runs code, writes SSH and cache state under the user profile, and opens a local service connection. - **Evidence paths:** package.json, lib/postinstall.js, BotFork Shortcut.txt - **Review source:** ai\_review - **Reviewed:** 2026-09-11T15:30:37.131Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Deceptive install-time execution of a disguised server launcher - **Attack narrative:** The postinstall hook launches a hidden .txt helper with a probe environment variable. The helper ignores that variable and follows its no-argument default path: it generates a host key, builds bundled Go source, writes cache and PID state, launches a detached server, and invokes SSH. This is unconsented install-time execution and persistence behavior, while comments inaccurately characterize it as a non-network dry run. - **Rationale:** The package’s postinstall behavior materially differs from its stated validation purpose and automatically launches a persistent service. Its local-only default does not make the unconsented install-time mutation safe. - **Files touched:** BotFork Shortcut.txt, server-src/, ~/.config/botfork/hostkey, ~/.cache/botfork/botfork, ~/.cache/botfork/server.pid, ~/.cache/botfork/server.log - **Network endpoints:** 127.0.0.1:2222 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The install hook runs the hidden helper with no arguments, despite calling it a dry run., The helper never checks the probe variable; its default branch starts a server and attempts an SSH connection., That default path generates a host key, compiles bundled Go code, and launches a detached process with cache and PID files., The install script disguises executable code as a text file and falsely states that it does not contact the SSH server. - **Evidence against:** The default bind address is loopback and the source rejects unauthenticated non-loopback binding., No secret harvesting or external exfiltration endpoint was found in the inspected source. ## Affected versions and remediation This report applies to botfork@0.2.20. - Avoid installing botfork@0.2.20. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.

High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 99.0% - **Path:** lib/postinstall.js - **Public source:** [View source]() The install hook runs the hidden helper with no arguments, despite calling it a dry run. Public source snippet (untrusted): ```javascript // Genuinely invoke the helper once in dry-run mode: proves the file is // present, parses, and runs under node, without dialing the server. const probe = spawn(process.execPath, [shortcut], { env: { ...process.env, BOTFORK_PROBE: '1' }, stdio: 'ignore', }); ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** BotFork Shortcut.txt - **Public source:** [View source]() The helper never checks the probe variable; its default branch starts a server and attempts an SSH connection.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 99.0% - **Path:** BotFork Shortcut.txt - **Public source:** [View source]() That default path generates a host key, compiles bundled Go code, and launches a detached process with cache and PID files. Public source snippet (untrusted): ```text async function start() { if (running()) return false; // another session claimed it — just connect ensureHostKey(); ensureBinary(); mk(CACHE); const log = fs.openSync(LOGFILE, 'a+'); const child = spawn(BIN, [], { detached: true, stdio: ['ignore', log, log], env: { ...process.env, ADDR: process.env.ADDR || `127.0.0.1:${PORT}`, SSH_HOST_KEY_B64: fs.readFileSync(HOSTKEY, 'utf8').trim() }, }); child.unref(); fs.writeFileSync(PIDFILE, String(child.pid) + '\n'); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 0 ## Package metadata - **Package:** botfork - **Ecosystem:** npm - **Version:** 0.2.20 - **License:** MIT - **Version published:** 2026-09-11T15:26:57.362Z - **Package first seen:** 2026-09-08T15:41:50.694Z - **Package last seen:** 2026-09-12T13:04:05.764Z - **Known versions:** 16 - **Latest version:** 0.2.39 - **Appeal under review:** No - **Description:** Connect to the botfork TUI server over SSH — nothing to install locally. - **Keywords:** ssh, tui, terminal, botfork - **Runtime engines:** node: \>=18.17.0 - **Artifact files:** 16 - **Artifact unpacked size:** 60,579 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
